Workers pose for a photo prior to raising the silver spire atop the 1 World Trade Center building in New York early Friday May 10, 2013. The 408-foot spire will serve as a world-class broadcast antenna. An LED-powered light emanating from it will be seen from miles away. When it is fully installed on the building’s roof, it will bring the iconic structure to its full, symbolic height of 1,776 feet.
